5 Essential Flat-Belly Foods

By David Zinczenko, with Matt Goulding -

QUINOA
Per ¼ cup:
170 calories
2.5 g fat
7 g protein
3 g fiber

For starters, anytime you choose a whole-grain product over one made from nutrient-stripped white flour, you wage war against belly fat. Penn State researchers found that dieters who ate whole-grains lost twice as much belly fat as those who stuck to white-flour products—even though they'd consumed the same number of calories. What's more, quinoa contains twice the belly-filling protein as regular cereal grains, fewer glucose-raising carbohydrates, and even a handful of healthy fats. So start your day off with a cup of cooked quinoa combined with a ½ cup of milk and ½ cup of blueberries—microwave for 60 seconds, and you have a delicious (and slimming) alternative to your traditional oatmeal. Bob's Red Mill Organic Quinoa won "Best Grain" in Men's Health's Best Foods Awards 2009.



KEFIR
Per cup:
174 calories
2 g fat
14 g protein
3 g fiber

Think of kefir as drinkable yogurt, or an extra-thick, protein-packed smoothie. In either case, this delicious dairy product is a belly-blasting essential. Beyond the satiety-inducing protein, the probiotics in kefir may also speed weight loss. British scientists found that these active organisms boosted the breakdown of fat molecules in mice, preventing the rodents from gaining weight. The researchers still need to prove the finding in humans, but there's no danger in downing probiotic-packed products. We like Lifeway Lowfat Blueberry Kefir—it contains L. casei, the same probiotic used in the study.

AVOCADO
Per avocado:
322 calories
29 g fat (4 g saturated, 20 g monounsaturated)
13 g fiber
4 g protein

Never fear this full-fat Mediterranean-diet staple: It's teeming with healthy monounsaturated fats (also found in olive oil), which have been linked to lowered LDL cholesterol levels and weight loss. In fact, a recent longitudinal study published in The New England Journal of Medicine found that the healthy-fat Mediterranean diet was more effective than a diet that avoided fats altogether—so go ahead and indulge!

EGGS
Per 1 large scrambled egg:
102 calories
7 g fat (2 g saturated)
7 g protein

A British study found that people who increased the percentage of protein-based calories in their diet burned 71 more calories a day (that's 7.4 pounds a year!). Jumpstart your metabolism as soon as you wake up with a protein-rich breakfast of scrambled eggs. (Go to eatthis.com for other great no-diet weight-loss secrets.)

* We used to have chickens that laid brown eggs. We sold them. There were people that refused to eat them stating that they weren't "real" eggs. Odd. Taste real to me, and the chicken coop they came from smelled "real".

GRAPEFRUIT
Per grapefruit:
104 calories
4 g fiber
2 g protein

A grapefruit a day in addition to your regular meals can speed weight loss. The fruit's acidity slows digestion, meaning it takes longer to move through your system, and you'll end up feeling fuller, and more satisfied, for longer. And the vitamin C-packed grapefruit works to lower cholesterol and decrease risk of stroke, heart disease, and some types of cancer.

*I'm always on the fence about Avacados and Eggs. One minute you hear they're bad, the next minute you hear they're great for you. I eat them. Natural stuff can't be bad for you right?
